setae, by the greater number of its root-leaves, and less leafy stem, and, 

 by the corymbose and smaller heads, and bluntish phyllaries. This 

 species is common on walls and rocks, and varies considerably, but is 

 probably truly distinct. 



" The third species, H. corymbosum, Fr., is the tallest and 

 most conspicuous of our British species, being from three to four 

 feet high, and occasionally having from thirty to forty heads of flowers 

 in one panicle. It is one of the commoner Teesdale species, growing, 

 in company with H. crocatum, Fr.^ on the heathy banks of the river 

 from Langdon Bridge to Newbiggin, and is found in similar situations 

 in both Wales and Scotland. 



" Hieracium cori/mbositm, Fr. Stem not producing a radical 

 rosette, very leafy, panicled or corymbose above ; leaves sessile, 

 ovate-lanceolate, acute, with numerous unequal teeth ; upper leaves 

 with a broad base strongly clasping, lower narrowed below, and 

 slightly clasping ; panicle, or corymb, very much branched, heads 

 numerous, six to forty ; pedicels scaly, glabrous or stellate, downy ; 

 involucres slightly narrowed below, glabrous, or slightly hairy and 

 setose ; phyllaries pale-edged, in regular rows, inner broad, obtuse, 

 outer smaller, narrow, acute, passing gradually into the scales of the 

 pedicels ; flowers deep yellow ; seeds chestnut-coloured, angular ; 

 pappus dirty white. Distinguished from H. crocatum and boreale, 

 Fr.j by its broader, more numerous, and more serrated leaves, which 

 clasp the stem, by its large, branched panicle, with numerous heads, 

 by its slightly narrowed involucres, and margined and hairy or setose 

 phyllaries. This species does not appear to be mentioned in Fries's 

 Monograph as British, but is included in the last edition of the Ma- 

 nual, and is, it seems, by no means very rare. Most likely a good 

 many specimens exist in herbaria under other names." — G. E. D.
